accomplishing this purpose, and providing means for adjusting the embossing elements for regulating'the depth to which the embossing is applied to the pole surfaces.

7 In the accompanying drawings illustrating a suitable embodiment of the invention:

Fig. 1 is'a plan view ofa pole embossing machine constructed in accordance with the invention.

Fig. 2 is an end elevation of the same. vFigs. 3 and 4 are, respectively, a longitudinal and a transverse section of the same on the lines 33 and 4-4 of Fig. 1.

Figs. 5 and 6 are perspective sectional views of short pieces of exemplary poles to be embossed in the machine;

The machine comprises a suitable frame including a table plate 1 on which three standards 2, 3, and 1 are mounted. Each of said standards is provided with a vertical guide slot in which pairs of bearings 5-5, 6-6

I and 7-7 are mounted, the bearings 5, 6 and 7 being supported on the. bottom walls of the guide slots of said standards. The main shaft 8 of the machine is journalled in said last-mentioned bearings and a shaft 9 is journalled in the bearings 5, 6?, and 7 the latter being supported upon compression springs 10 resting on the bearings 5, 6, and 7,'and adjusted to desired position relatively to the latter by means of set screws 11.

Mounted on the shafts 8'and 9 in the spaces between the standards 2, 3, and 1 are pairs of embossing rolls 12 and 13 between which the poles to be embossed are engaged, and by. means of which they are moved longitudinally through the machine.

At opposite sides of the standards 2, 3, and I 4 are platforms 14 and .15, suitably mounted upon the plate 1 and upon each of said platforms 14 and 15, pairs of parallel guide plates 16 are mounted for engaging side faces of poles for guiding the same accurately through paths of travel properly aligned with the em- 1929, Serial No. 371,433.

bossing surfaces-of the pairs of embossing rolls. I

Between the plate 1 and the platforms 14 and 15 aregas-burners 17 and 18 disposed in the horizontal plane of'theaxis of the'eshaft 8. Similar burners 19 and 20are supported upon a platform 21 disposed above the platform 14, the burners 19 and 20 being disposed in the horizontal plane oftheaxis of the shaft 9, all of said burners being arranged to direct flames against-the surface oftheembossing rolls and eachthereof being connected with sources: of air and gas under pressure in a well-known manner.

At one end of the shaft 8 there is mounted I a large spur-gear wheel 22 which meshes with a spur-pinion 23 on the drive shaft 24 disposed below the plate 1 and which is jour-' nalled in bearings 25, only one of which is shown, said bearings being mounted in .-ver

tical guide slots in hangers 26secured to the lower face of the plate 1 and supported upon set-screws 27 which hold them firmly upon the upper ends of spacing members 28 interposed between the bearings 25 and frame elements secured to the table'lto thus cause the pinion 23 to properly-meshwith the spurgear 22. On the shaft 8 there is mounted a spur-gear 82 which meshes with a similar gear 33 on the shaft 9 for driving the latter at the same speed as shaft 8.

' The shaft 2 1' is equipped at its other end 2 portion with a series of pulleys 29, 30, and 31 of different diameters for associating the' 7 shaft 8with companion pulleys for rotating the same at different speeds according to the 1 depth of the embossing and the use or elimination of heat in efi'ecting the same, it being obvious that if the embossing is to be effected by means of pressure only, the polesmay be passed through the machine at higher speed than if heat is used. Furthermore, if the embossing is to be effected by heat and pressure, and-is to be shallow, the poles may be passed through the rolls more rapidly than if the embossing is to be deep as the absorption of heat from the embossing rolls is less rapid for shallow than for deep embossing. In operation, the shafts 8 and 9 and the embossing rolls rotate continuously. -The p operator feeds poles alternately to the two pairs .of embossing rolls which emboss each s pole along diametrically opposed surface portions so that each pole must be passed through the rolls twice to emboss four surfaces thereof. 7

The instant machine, as shown, is adapted for embossing poles of polygonal cross-section as exemplified'in Fig. and Fig. 6, the

em'bossing'rolls shown being easily interchangeable for others adapted for embossing poles of whatever cross-sectional. V shape desired.

We claim as our invention: A machine of the kind specified including a support, standards mounted thereon and provided with guide slots, pairs of bearings mounted in said guide slots, aspring interposed between each pair of bearings to maintain them normally spaced apart, a set-screw in each standardfor adjusting one of the V bearings of each pair relatively to the other against the action of said spring, a pair of parallel shafts journalled in said bearings,

one thereof being permanently positioned and the other thereof adjustable relatively to the same by adjustment of the aforesaid bearings against the act-ion of said springs, a pair of embossing rolls onsaid pair of shafts between said standards and opposed to each other, means for continuously heating said rolls, guides on saidsupport o-peratively associated With said bearings, means for driving the non-adjustable shaft,and guides for the article-to be embossed disposed in front of and behind said embossing rolls and in alignment with the space therebetween in which the article travels while being embossed. a Y In testimony whereof, we have hereunto set our hands this 5th day of June, 1929'.
